Grow Rubus idaeus 'Joan J' (Red Raspberry 'Joan J') for heavy late-season harvests on current-year canes with fewer thorns to deal with. You will get the best flavor and the most berries when you plant it in full sun; in hotter areas, light afternoon shade can help keep fruit and foliage looking their best. Set plants in fertile, slightly acidic, well-drained soil that stays evenly moist, and mulch to hold moisture and reduce weeds.
For simple, reliable fruiting, treat it as a one-crop primocane raspberry: cut all canes to the ground in late winter before new growth starts. Fresh canes will emerge in spring and produce a big crop from late summer until frost. If you want a second, earlier crop, you can leave some canes to fruit the following summer, then remove those spent canes after harvest.
Give this plant room and support. Space plants so air can move through the canes, and use a trellis or stakes to keep growth upright and accessible. Water deeply during dry spells, especially while berries are swelling, and avoid soaking foliage to help reduce disease pressure.
Pick often as fruit ripens, and enjoy fresh eating, freezing, or preserves. With steady moisture, annual pruning, and good sun, 'Joan J' will reward you with long-season, high-quality red raspberries year after year.
